In software improvements and upgrades, many people will pay attention to Color Grade, Color Correct, Chrome Key, and many other FX improvements. DIfferently, I might focus more on things like software architecture and the underlying interface. Because if we focus on improving FX firstly, when in the future we have to upgrade the software architecture and the underlying interfaces, we may have to rewrite those FX and that is a waste of resources. Therefore, I usually suggest that the software architecture and underlying interface should be done first, and then carry out the writing of new Native OFXs.

=============================

So this time I'm going to talk about the architecture and interface improvements of Event FX.

In Vegas, Event FX is the most common FX level. Unfortunately, it can only access its own event. This makes Event FX a Filter rather than a Compositor. This limits the use of many advanced plug-ins in Vegas, such as Continuum and Sapphire. (The difference of Filter and Compositor : ...)

A typical example I've come across in teamwork is the BCC Layer Deformer.

I have 6 tracks in Premiere, and I place a texture on each track, and I'm going to place them on the 6 surfaces of the cube. In Premiere, All I have to do is applying the BCC Layer Deformer to one of the events and then select the appropriate Premiere tracks for each of the 6 surfaces in Effect Control. It was pretty simple :

However, in Vegas, since Event FX cannot access other tracks/layers, so other tracks cannot be listed in the Effect Control drop-down list, so this Effect cannot be completed in Vegas at all :

The Vegas Event FX bug severely limits the functionality of advanced plug-ins, not just BCC Layer Deformer, There are also BCC Pin Art 3D, BCC Particle Array 3D, BCC Particle Emitter 3D and so on. Vegas really need to make Event FX access multiple other layers/tracks. 

This improvement needs modifing in Vegas' software architecture and underlying interface, which is not easy, but it really should be noticed and tried.
